Determine the gain in gravitational potential energy when a 4.00 kg rock is raised 18.000 m.

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
